Model 1: Included age, sex, and study year.

Model 2: Further adjusted for race, marital status, and history of angina, diabetes, heart failure, hypertension, stroke, and CABG.

Model 3: Further adjusted for clinical presentation including day of week admission, time of day, chest pain, AMI order (intial vs. prior), AMI type (Q wave vs. non-Q wave), and AMI location (anterior vs. inferior/posterior).

Notes: Information on DNR and STEMI was recorded beginning in 1991 and 1997, respectively; therefore, these variables were not included in regression model #3
